DIY: Populating Next Right Pointers in Each Node

Explore how to populate each next pointer in a perfect binary tree to point to its next right node. This lesson guides you through implementing a function to connect these pointers efficiently, helping you understand tree traversal and pointer linkage for coding interviews.

We'll cover the following...

Problem statement

You are given a perfect binary tree where all the leaves are on the same level and every parent has two children. We have added an additional next pointer to our TreeNode implementation. ...
